How should I seal it up? Take the xover off and put silicone on it? It's not leaking bad at all bc if I never seafoamed it I would have never known it was leaking. Is there a way to test for exhaust leaks?

And nothing but 93 octane. Also my bbv broke so I was only getting 2psi Max. So I took that hose off and plugged it and left bvv venting to air and now I get full boost now (10-11psi). I don't have any vac leaks
